TO ALL WHOM IT MAY CON CERN:

Be it known that I, HENRY MALLEY, of Chicago, in the county of Cook, and State of Illinois, have invented a n-ew and useful improvement on Lifting Machine; and I do hereby decla-re that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure I is a perspective representation of my improved lifting machine.

Figure II is a longitudinal elevation of the cross-tie attached to the door, showing how the central guides are connected.

Figure III is a plan view of the same.

The nature of my invention consists, first, in placing the reverse pulley between tne spiral grooved. drums;y and connecting it with suitable gearing, in order that the brake used for checking the'motien of' the machine may be operated by means of a chain or rope passing over the reverse pulley and down between the pla-t' me; in a convenient position to be 'reached from either by a person standing therein. This first arrangement is important from the factthat the platforms cannot be successfully operated when the chain passing over the reverse pulley is arranged in any other position than between them, because a person passing up or down inthe platforms must necessarily be able to control their direction. Second, in connecting and supporting the central guide by means of cross-ties and knees, in order that each section of the machine may be arranged to suit the diiferent heights of stories in the building in which it is placed. The entire machine, as constructed, forms a simple and effectual means of elevating and lowering goods and merchandise in warehouses and hotels of one oi*- more stories.

In-the drawings, only one story is represented, I being the door. A A represents the frame supporting my lifting machine. G G show the platform boxes Vin which the merchandise is put when the same is to be elevated or lowered. F shows the right and lefthand spiral grooved drums, on which the rope or chain D operates. These drums-F have the usual suitable shafts, resting inboxes attached to the upper part of the 4frame A A. B represents cog-wheels attached to the shafts passing through the drums F. These cog-wheels are made to operate the drums in the proper direction for lowering either of the platforms G, While the other is passing upward, by means of the small cog-wheel@` attached to the shaft 9, passing through thepulleys 3, 3, 4, 3, 2, the pulley 4 being the only one secured to the shaft 9, the other pulleys being loose ones, used-for the convenience of changing the direction of the belt. z' represents inclined standards terminating in the circular head 10, in which are made bearings for supporting the shaft o, to which' is attached the reverse pulley 15. L is the chain or rope passingover the reverse pulley l5, and around under the pulley K, used. for reversing the direction ofthe platforms G and operating the brake. l? shows the bevel cog-wheel attached to the shaft 0, which operates the bevel cog-wheel Q attached to the shaft r. n shows the tie secured to the braces which support one end of the shaft r, the other end being supportedl by the box U, resting upon the cross-*tie Vf S shows the ratchet-wheel which operates the rack t attached.to the slide X operating in the loops jj. W the band-guide attached to the slide X, used for throwing the band on and off of the tight and loose pulley 3, 4, 6 represents the brake-bar attached to the slide X by means of the joint 7, extending through a cap attached to the cross-bar 8 and connected permanently to the brake 5. J J J represent vertical guides in which are made the grooves 11, for receiving tongues projecting outward from the platforms Gr, in order to prevent a lateral motion. H shows the cross-tie secured to the iioor I, by means of bolts or otherwise, in a substantial manner. The object ofthis is to form a substantial support forv the ends of the central guide J. This arrangement is necessary, because when the machine is adjusted in a building containing more than one door, the central guide J would otherwise be too weak to properly support the platforms Cr in their upward and downward passage. But by using a central guided for each story, and connecting the same to the crosstic H by means of the cast-iron elbows m with suitable bolts, a strong support is provided for guiding the inner sides of both platforms.' Itnill be seen that the opposite ends of the drum F are placed nearly over the centre of the platforms C. Thisis done in order that the ropes D attached to the platforms G at E may be as perpendicular as possible when 'the platforms areelevated to their extreme height.

sigma 7 Any power may be used for elevating which will properly operate the `pulley 4. Lwo bands must be used, running in opposite directions, in order that the motion-ofthe platforms may be reversed, which may be accomplished by turning the reverse pulley 15 by means of the chain L; this will operate the devices above described so as to move the band-shifter W far enough to throw the bonds on or off the pulleys 3 4 in the usuel manner, at which time the brake 5 will operate against the tight pulley 4' andl check its motion. The weight to be raised con be put in platform boxes G in the usual manner.
